For those who care, a
30-second commercial (Nico link) aired right after today's Vampire Knight episode on TV Tokyo.
Some new animation is shown, along with actual voices and a part of the OP sung by Shuuhei Kita (that song sure is nothing like the OP for Persona he's done!). I was fairly surprised when I first read that Kazuhiko Inoue would voice Nyanko-sensei, but he sounds like he can pull it off just fine. As for Hiroshi Kamiya as Natsume... it's the return of Takemoto!
Ahh, can't wait till next Monday.
